Just out of interest I searched Harker for the word 'fraud'. He uses it once in connection with a reform (fair enough). In connection with folklore, he uses it when he discusses an 18th century scholar and antiquarian Ritson. He praises Ritson for seeking to sort out authentic material as opposed to the less authentic material offered by Percy and a number of people who seem to have published material Ritson regarded as less scholarly and authentic. So concerns about authenticity fo back to the 18th century. Of course somebody may know more about Ritson than I do and may say Harker was wrong about him and about Percy.

Similarly I searched for the word 'greed' and did not find it anywhere.

Polemic Harker may be but not quite that crude? Asking here, not asserting.
